Sorry, I made these exactly by your recipe, but they didn't turn out well. They were too dry but it could have been the peanut butter I used. Nobody in my family ate them and I ended up throwing them out.
This recipe tastes pretty good! But its best qualities are in its simplicity- one bowl, one spatula, 4 ingredients and 20 minutes of your time (including clean-up!) I made this in my toaster oven and it only took about 10 minutes to bake the cookie, so be cautious leaving it for 20 minutes without checking on it. Nice snack idea-- thanks!
